Call +1 (866) Si WAFER


Silicon wafers are graded based on the specifications to which they were manufactured. Both prime Si wafers and test Si wafers are round and shiny, but certain test wafer specifications are wider than Prime wafer specifications. For instance, the semi-standard thickness for a 100mm silicon wafer manufactured to test standards is 475um - 575um, however, the semi-standard thickness for a 100mm silicon wafer manufactured to Prime wafer standards is 500um - 550um. Note the tighter thickness requirement for the prime silicon wafer.
